On your computer, install any program that "reads" CW -- Hamscope, or CWGet, for example.

In whatever way you want, hook up your key or paddle, and feed your "sent signal" into the computer's sound card. You could use a code-practice buzzer and a microphone, or your rig's keyer and sidetone (without transmitting) and a cable from the rig's headphone output to the computer's "Line In" socket.

If the computer program can "read" your sending, you're doing fine. If not, you'll get instant feedback on which characters it understands, and which ones it doesn't.
